Abstract

PURPOSE: To provide a three-dimensional shape model forming method and system to be able to form the three-dimensional shape model with the small mandays.

CONSTITUTION: Two-dimensional graphic information 101 and 111 of the three- dimensional object and a three-dimensional basic shape model 102 in which the basic shape is close to the three-dimensional object are inputted. The corresponding information of feature points 105 and 115 on the two-dimensional graphic information and a control point 107 on the three-dimensional basic shape model is inputted. A deforming program 108 deforms the three-dimensional basic shape model 102 so that the control point 107 on the three-dimensional basic shape model can be coincident to the feature points 105 and 115 on the two-graphic information and a three-dimensional shape model 109 of the three- dimensional object is formed. Thus, by using the two-dimensional graphic information of the three-dimensional object, the three-dimensional shape model is formed.
